discussed several times here. I had the same. It has gone after installing Acura 3DMAX v3 + KERNEL UNIVERSAL V3 FINAL by Acura too.
As i understand happens by low voltage on screen unlock. Then you block *wake on lan* and/or tiwlan_wq driver.

you can not.
try to put minimal MHz at about 300. use SetCPU. or try higher. you will reduce the hangings. but for me the Acura kernel did the job.

If you are on stk kernel it is already set to 300 minimum...you might take a look at your build.props. and check wifi scan interval setting change it to 30 if not already and see if it make a difference.

I had the same problem too on stock ROM v21E, that was only rooted...It doesn't happend every time but about every 10 - 15 attempt to turn on the WiFi. It was very annoying when I must restart my phone on that time to be able to use my WiFi again.Strange that after restart everyting works OK...I'm using custom ThiaiZO3D ROM now and I don't have that problem anymore. I think it's just kernel related...

I have the same problem too, when its on v21e(DNA3.3.3). event the bluetooth does that too.
now i am on v20g(stock rom). wifi problem gone. but the bluetooth still down occasionally.

2.7.1 that version runs over 2.1 A
But you'll have ghost calls for sure, but try the 2.8 with 21p baseband if you're in America if not You use 2.1e baseband and it's In think the best Rom so far.

Thanks for info. I my phone doesn't go to download mode so I can't rewrite different baseband. Or maybe it should be blank screen? Before I had o2x and it showed download mode.

Just go to the WiFi advanced settings and deselect the option for the WiFi to turn off when the screen goes off. You can choose WiFi sleep policy to "never" instead, which doesn't consume that much battery like many people think. It's quite the opposite:

I do agree with you on battery point. Well he already written he is using Stock ROM GB 2.3.3.
@ayazm.140895
Check your GPS also, as It can drain your battery faster. And also try to check your battery health (means how old its is?).
One more thing I want to say kernel also play a fair part in performance and battery backup. So you can try and check with different kernel.
Guys, I'm using Franco kernel#4 and I can't unmount my sdcard after turning on usb mass storage device and when I disconnect the usb cable, my phone doesn't recognize my sdcard. I have to reboot my phone to access my sdcard on my phone. Nowadays I get a “sdcard removed error“. I have to reinsert my sdcard. My battery is almost 1and 1/2 years old. I have 24 wake-ups from android (system itself)

Unexpected shutdown during call!

Hello everyone, I'm facing a issue i.e. unexpected shutdown during a call ( while making a call and recieving a call) It happens once in a two days or so. Its really annoying! I'm using stock gingerbread rom, rooted, no modified kernel and no a2sd. If you could help me. I'm facing this issue even on gingersnap 2.3 by neko.

Are you overklocking your CPU?
If so this could be the reason for your problem
No, i don't overclock. I hate overclocking! I use rooted stock rom and in gingersnap there was a initd.d script, which was used to overclock, i just edited that script to bring it normal frequency i.e. 600mhz!

Do you go to places where signal is low ? This might be the most important cause of that draining.
Nope. Coverage in my country is always 3/4 bars.

Did you try to flash a different baseband, different firmware, different builds ?
I attempted to flash a new rom before. But it bricked my phone. I luckily recovered from it. Its just so confusing flashing on LG...
Sent from my LG-P920 using xda app-developers app
Driver setup is a bit tricky at first but once it's done, it's done and you can use Fastboot, Flash Tool, .kdz flashing, whatever.
